PPWR—the new Packaging and Packaging Waste Regulation proposed by the European Commission—aims to reduce packaging waste, promote the circular economy, and mitigate adverse environmental and health impacts through stringent packaging standards and waste management measures. The EU PPWR regulation will officially take effect in August 2026, applying to all packaging and packaging waste placed on the EU market, requiring that all packaging types and materials comply with its provisions and bear uniform labels indicating their material composition. Among its various requirements, the most significant is the establishment of mandatory recycled content targets for plastics.
These explicit requirements for recycled materials have made the recycling and reuse of waste plastics an essential component for plastic packaging, with plastic pyrolysis technology—as the core pathway of chemical recycling—playing a pivotal role in the circular utilization of waste plastics.
Continuous pyrolysis systems are transforming what was once considered an "environmental burden"—waste plastics—into a diverse range of high-value-added products. Through the pyrolysis process, waste plastics are decomposed in oxygen-free or oxygen-deficient environments into three primary products: fuel oil, solid residues, and combustible gas. These products find broad application prospects in the energy, chemical, and materials sectors, and are progressively establishing a comprehensive resource recycling system.
Pyrolysis oil, the core liquid product of waste plastic pyrolysis, is a complex mixture containing various organic compounds. With a high calorific value, it can be directly used as an alternative fuel in industrial boilers, steel plants, and cement kilns, or, after simple refining, as fuel for marine vessels and agricultural machinery. This "produce and use" model represents a typical application of plastic pyrolysis to fuel, offering a low-barrier resource utilization solution for small and medium-sized enterprises.
However, because raw pyrolysis oil contains significant amounts of unsaturated hydrocarbons, halogens, metals, and other impurities, it requires refining and upgrading before serving as transportation fuel. Currently, mainstream deep-processing pathways include distillation and fractionation, hydrotreating, and catalytic upgrading, which convert it into higher-value chemicals for use in the chemical industry.
The highest-value application of pyrolysis oil ultimately points to a complete "waste plastic-to-new plastic" cycle. Refined pyrolysis oil can serve as feedstock for steam pyrolysis units—similar to naphtha—and can subsequently be repolymerized to produce new plastic products. This pathway achieves "same-grade, high-value" utilization of waste plastics, avoiding the "downcycling" problem inherent in mechanical recycling. For instance, the Danish BASF project, which employs Niutech's technology and equipment, has already established a complete closed-loop pathway of "plastic → waste plastic → resin → plastic."
The non-condensable gas generated during pyrolysis is rich in small-molecule hydrocarbons such as hydrogen, methane, ethylene, and propylene, and possesses a high calorific value, offering significant energy utilization value. A key feature of most pyrolysis systems is that this gas is combusted on-site to provide the heating energy required to sustain the pyrolysis reaction, making the process more energy-efficient. Some systems also utilize surplus gas for power generation, achieving energy self-sufficiency and reducing external energy consumption.
With the implementation of PPWR, the high-value application of plastic pyrolysis products is evolving from the primary model of "waste plastic to oil" toward a deeper value upgrade of "waste plastic → high-value chemicals → new materials." Industry leaders such as Niutech are reshaping the future of chemical recycling of waste plastics through this comprehensive green recycling solution, and are also redefining the way plastics are processed and the value of waste plastics. As technologies such as pyrolysis and catalytic pyrolysis continue to improve, the resource potential of waste plastics will be further unlocked, providing dual benefits for environmental protection and economic development.
